hi all
the reboot and halt scripts stop when trying to unmount the /usr partition.
the script is terminated and the system does not reboot or halt properly.
very nasty...
a "fuser -vm /usr" command at this point shows the following:
USER PID ACCESS COMMAND
/usr root 8471 ....m. S01REBOOT
this means, that a shared library is in use by the rc script itself. i
discovered, that the use of nss_ldap is the reason for this. tell the system
in /etc/nsswitch.conf to use ldap and this phenomenon happens. i also
discovered that when the whole filesystem is in one partition, it does NOT
happen. it only happens when /usr is on a separate partition (usually on
servers).
doing a "ldd /lib/libnss_ldap-2.2.5.so" shows the following:
libldap.so.2 => /usr/lib/libldap.so.2 (0x40024000)
liblber.so.2 => /usr/lib/liblber.so.2 (0x40055000)

/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x80000000)
as you can see there are several libraries loaded by lib_nssldap that reside
on /usr/lib. copying these to /lib resolves the problem.
many of the postings here regard desktop programs in mandrake linux. i
understand, that this is important to mandrake. but wouldn't it be nice to
play an important role in the server market? this is not the only issue when
using ldap with mandrake (see my other postings on this list). i hope,
mandrake will fix these bugs as soon as possible.
these problems were not difficult to find (why did nobody at mandrake test
this? i think the beta tests are no good for such features because most of
the freaks out there only test their video players etc.)
ldap is important when trying to replace windows servers with linux/samba and
manage user accounts. try to improve quality please...
thank you
