The name of the mounting user is written to mtab so that he can unmount the file system again. This option implies the options noexec, nosuid, and nodev (unless overridden by subsequent options, as in the option line user,exec,dev,suid). users Allow every user to mount and unmount the file system. This option implies the options noexec, nosuid, and nodev (unless overridden by subsequent options, as in the option line users,exec,dev,suid).

The question still is why did this happen? Thank you very much for your help that saved me from starting all over again with the installation. Michael -- [EMAIL PROTECTED] mailing list

That will allow any user to unmount /var at any time (as long as there are no open files). Just checked out the man page for mount. It says: The full set of options used by an invocation of mount is determined by first extracting the options for the file system from the fstab table, then applying any options specified by the -o argument, and finally applying a -r or -w option, when present. This would imply that you need to add exec (and maybe suid) to those flags. But if defaults doesn't apply then the out-of-the-box fstab which only contains noatime should not work. Try adding exec and if it works you may have come across a bug in mount. Jason -- [EMAIL PROTECTED] mailing list

To be sure I remounted /tmp without nosuid and noexec. It still won't emerge bash or maybe anything thats got to be ./configure -d Michael -- [EMAIL PROTECTED] mailing list

Your error matches the one I get every time I try to execute a script in /tmp, as I often forget that I have that partition mounted noexec. -Eamon -- [EMAIL PROTECTED] mailing list
