[Bassetlug mailing] unison issues SGID?

[Mark Pengelly - online]

OK working this out I think:

markp at markp-study-home:/markp/accounts$ ls -l
total 28
drwxr-xr-x 3 markp users 4096 2008-07-09 20:30 directoryname

markp at markp-study-home:/markp/accounts$ sudo chmod -v g+s directoryname
[sudo] password for markp: 
mode of `directoryname' changed to 2755 (rwxr-sr-x)

this works.

Next Question is:

will setting the SGID on the directories on one side of the sync root
adversely affect the directory properties on the other root (ie the ones
accessed as samba shares), where I guess samba is controlling this using
the create mask. I'll hold off til i know!
