2 The entire network stack has been replaced. This requires two updates.
3 First, BEFORE rebooting, either before or after rebuilding the system,
4 copy the following new configuration files from /usr/src/etc into /etc:
7 # cp hosts inetd.conf named.conf nsswitch.conf /etc
9 Second, AFTER rebooting, set up a new network configuration for your
10 system. Run netconf(8) and and follow its instructions:
14 If you previously configured your network statically and you forgot its
15 settings, take a look at /etc/rc.network. That file and /etc/inet.conf
16 are no longer used now. See the ifconfig.if(5) manual page for more
17 information about how network settings are specified going forward.
20 Edit your /etc/rc.conf to set rc_configured to YES. If you do not,
21 your system will refuse to enter multi-user mode after the next reboot.
22 You can then still make the same edit from single user mode, but that
26 Because of naming conflicts, the MINIX 3 service(8) utility has been
27 renamed to "minix-service". After successfully rebuilding the system
28 *and* rebooting (no earlier!), remove the old service utility:
32 Better yet, use the postinstall(8) command to remove all files marked
33 as obsolete. It is not a bad idea to do this every now and then:
35 # postinstall fix obsolete
37 ..but only ever after the reboot! Either way, deleting the old service
38 tool will avoid conflicts with the same-named NetBSD utility later on.
41 Before starting a build, you will have to update your master.passwd and
42 group files in /etc. This is needed because we have switched over from
43 the old set of MINIX users and groups to the new set of NetBSD users
44 and groups, as needed by various imported tools. Follow these steps.
46 1. Make a back-up copy of your old master.passwd and group files:
48 # cp /etc/master.passwd /etc/master.passwd~
49 # cp /etc/group /etc/group~
51 2. Install /usr/src/etc/master.passwd to /etc/master.passwd, and
52 install /usr/src/etc/group to /etc/group. If you have NOT created
53 any local user accounts yourself, for example because you are
54 upgrading a fresh MINIX 3 installation right away, all you need to
55 do is copy over those two files:
57 # cp /usr/src/etc/master.passwd /etc/master.passwd
58 # cp /usr/src/etc/group /etc/group
60 If you DO have custom user accounts or groups, you need to merge
61 their lines (and only those!) into the new master.passwd and group
62 files manually. If you are unsure whether you have such custom
63 entries, you can use the following commands:
66 # git show 68804c2:etc/master.passwd | diff -u - /etc/master.passwd
67 # git show 68804c2:etc/group | diff -u - /etc/group
69 This should show any changes compared to the old two templates. If
70 you have such changes, you need to reapply them after copying over
71 the new two templates. The following procedure shows one approach:
74 # cp /etc/master.passwd /tmp/my-passwd
76 <remove any lines from /tmp/my-passwd that have no password>
77 # cp /usr/src/etc/master.passwd /etc/master.passwd
78 # cat /tmp/my-passwd >> /etc/master.passwd
81 ..and follow a similar procedure for /etc/group.
83 3. Once the new files are in place, update all derived password files:
85 # pwd_mkdb -p /etc/master.passwd
87 If you did everything right so far, the following command:
89 # postinstall check uid gid
91 ..should show "postinstall checks passed: uid gid" and no failures.
93 4. Now perform a full build as usual:
98 As part of the build, all /dev files will get new proper ownership.
100 5. There may still be files that are owned by users and groups that now
101 have been renumbered. It is advisable to run at least the following
102 three commands to apply the renumbering to the most common files:
104 # find / -user 2 -exec chown bin \{\} \;
105 # find / -user 5 -exec chown uucp \{\} \;
106 # find / -user 9998 -exec chown games \{\} \;
108 If you have installed custom programs, you may want to check whether
109 they are not affected by the change. This should be rare, though.
111 Until a subsequent reboot, various running services will show up in
112 ps(1) output and /proc as owned by "postfix". This is no problem.
115 MINIX 3 did not import NetBSD's passwd.conf file, which makes the
116 userland fall back by default to the old, broken UNIX password hashing
117 algorithm. Among other problems, it truncates passwords to the first
120 Please install /etc/passwd.conf and reset your passwords with passwd.
123 Some tools are required to generate the locale resources which are
124 embedded into libintl, which is why you need to run the following:
126 for t in gencat locale mkcsmapper mkesdb mklocale
128 make -C /usr/src/usr.bin/${t} all install
131 Then the usual "make build".
134 In order to use the new Unix98 PTYs, and to ensure that the test set
135 continues to pass, please add the following line to your /etc/fstab:
137 "none /dev/pts ptyfs rw,rslabel=ptyfs 0 0"
140 As the ABI went under heavy changes it is not possible to do a source
141 upgrade (make build) between:
