Pinned topic Different mount options on SunOS and Linux

‏2006-08-11T07:42:56Z |
Hi,

we've got SunOS (5.9) and Linux (RHEL4u3) build machines, all running CC6.

We see that VOBs are mounted with different options on Linux and SunOS,
especially, Linux adds a "nosuid" mount option, while on SunOS "setuid" is
added.

This causes us trouble during distributed builds on the Linux machines,
because the remote machine(s) gets an "Operation not permitted" error when
trying to execute a suid root binary from one of the VOBs. If I restrict
the build to one machine only, everything is fine, though.

I tried replacing the tag for that particular VOB to explicitely add
a "suid" mount option, but unfortunately Linux still adds the "nosuid"
after my "suid" option, thus making it useless.

Any hints?

Bye...

    It was my impression that you get to make these decisions at siteprep
    time. Maybe your Linux install area was siteprepped differently?

    It was my impression that you get to make these decisions at siteprep
    time. Maybe your Linux install area was siteprepped differently?

    Hmm, don't know. I didn't prepare the release area myself, have to ask.

    OK, I checked the release areas of both Solaris and Linux. They're
    configured identically.
