The libc5 version in hamm is patched to address utmp and wtmp in a
libc6-fashion.
After upgrading to libc6, you must truncate utmp and wtmp by renaming them
to ?tmp.libc5 and then "touch"ing new files like this:
cd /var/log
mv wtmp wtmp.libc5
touch wtmp
cd /var/run
mv utmp utmp.libc5
touch utmp
shutdown -r now
The reboot is necessary to make sure that:
- all programs still linked against libc5 will now use the modified libc5
that uses the libc6 types;
- they write to utmp and wtmp files that contain _only_ libc6-style
records. If the old and new styles get mixed, the files conform to
neither format.
You only have to do this once, when you first install the libc5 from hamm
(contrarily to what the postinst tells you every time you upgrade to a
slighty newer version in hamm.)
Cheers,
Joost
