While tryning to configure samba using linux conf, after quite a bit off trying different config to connect to a NT4.1 ws patch 3.0, I got my /etc/smb.conf file corrupted. (the file was still readable, but a lot of garbage was addded to it) :-))
This was reported once on the linuxconf mailing list, but we can't replicate it.
I have exactly the same problem with linuxconf at RedHat 6.0 and 6.1 Eventually, linuxconf will corrupt /etc/smb.conf I can not give exact sequence of keys to be pressed, but every time after some extensive configuration work linuxconf corrupts the /etc/smb.conf I had this problem three times, since then I do not use linuxconf for configuration any more. Linuxconf either crashes (much more often when used with grome frontend), or corrupts the files. If you want I can try to reproduce the problem with /etc/smb.conf again.
I can't reproduce this with linuxconf-1.16r10. This will be released as errata when testing is completed. I suggest upgrading when it is available.
1.16r10-2 released
