Thread: Linux MANDRAKE startup startup script is broken ?
Hi,
I had a request from bulgarian user of postgres. He complained
about non-working locale. His system is MANDRAKE 7.0 which comes
with postgres 6.5.3 I believe. After several messages we found
that problem was in startup script /etc/init.d/rc3.d su -l postgres -c 'postmaster .......'The problem was '-l', after
removingit all problems were solved !
I'm not an expert in su, at least I don't know what '-l' is supposed
for, but it's worth to describe the problem and let people from
MANDRAKE to know.
Regards,
Oleg

?!?!?!? Do something for me: add a couple of lines in
/etc/rc.d/init.d/postgresql after the postmaster start:
su -l postgres -c 'set >/var/lib/pgsql/envvars-l.lst'
su postgres -c 'set >/var/lib/pgsql/envvaqrs-no-l.lst'
And e-mail me the two '*.lst' files out of /var/lib/pgsql.

The same problem should manifest itself in RedHat, which is what I build
the RPM's for. Mandrake has been taking the RedHat RPM's and using
them, with modifications, up till now, so, if I fix this in the RedHat
RPM's, the Mandrake RPM's will follow from Mandrake shortly.

Switch -l cause su to emulate login procedure, i.e rewrite all environment.
