Full Text Bug Listing

After upgrading to nfs-utils-1.1.2 following bug #217977, I have the problem
above on two out of three clients. Trying to restart the service after emerging
version 1.1.2 yields the error message below:

# /etc/init.d/nfsmount restart
 * Caching service dependencies ...
 *  Can't find service 'rpc.idmapd' needed by 'nfsmount';  continuing... [ ok ]
 * Unmounting NFS filesystems ...                                        [ ok ]
rpc.idmapd
 * ERROR:  Some services needed are missing.  Run
 *         './nfsmount broken' for a list of those
 *         services.  nfsmount was not started.

Subsequently trying to start the service yield the same error. './nfsmount
broken' yields:

# /etc/init.d/nfsmount broken
 * Caching service dependencies ...
 *  Can't find service 'rpc.idmapd' needed by 'nfsmount';  continuing... [ ok ]
rpc.idmapd

and no remote filesystem is mounted.

As far as I understand rpc.idmapd is needed only for nfs4 mounts, which I do
not have, and is added to nfsmount dependencies in the 'if' block between lines
10 and 15 of /etc/init.d/nfsmount through some arcane 'awk' magic which I don't
pretend to understand but must obviously be wrong.

The client which yields no error is testing baselayout-2 and openrc, the ones
yielding errors are still on stable baselayout-1.

Reproducible: Always

Steps to Reproduce:
1. Upgrade to net-fs/nfs-utils-1.1.2
2. /etc/init.d/nfsmount restart
Actual Results:  
The nfsmount service requires missing rpc.idmapd service.

Expected Results:  
Mount remote nfs filesystems normally

should be fixed in cvs now

Nope, it doesn't work. Same error as before.

Fixed it here.  Not to be insulting, but did you do an etc-update to replace
the init.d script?

No insult taken. Yes, I did. I'll try now on the 2nd affected system and report
my findings.

I can confirm it also on the second computer: problem not solved.

Thanks to the tutorial at
http://www.oracle.com/technology/pub/articles/dulaney_awk.html
I think I can now understand the 'awk' statement in the ebuild and maybe what
is the problem with it. Let's see if I got it right:

Line 11: awk '!/^[[:space:]]*#/ && $3 == "nfs4" { exit ($4 ~ /sec=krb/ ? 10 :
20) }' /etc/fstab
It check each line of /etc/fstab not startint with whitespace or '#' and for
each line in which the third field is "nfs4" it exits with 10 if the fourth
field contains sec=krb and with 20 if it does not.

Line 12: local ret=$?
It assigns the exit value of the 'awk' command to local variable 'ret'

Line 13: [ ${ret} -eq 10 ] && myneed="${myneed} rpc.gssd"
If 'ret' is equal to 10 then add rpc.gssd to the dependancies

Line 14: [ ${ret} -ne 20 ] && myneed="${myneed} rpc.idmapd"
If 'ret' is _not_ equal to 20 then add rpc.idmapd to the dependancies

I think that the error is in this line: shouldn't it be [ ${ret} -eq 20 ], that
is add rpc.idmapd if we have an nfs4 filesystem _without_ kerberos security? In
the current way, if no nfs4 filesystems are found, 'awk' returns some value
(for no matches found) which is nor 10 (thus not triggering the first
conditional), neither 20 (thus _triggering_ the second conditional).

I hope I got it right.

it was supposed to be changed to -eq but i missed that in the previous commit
