after init all /tmp file has been removed

UNIX Solaris
1

I'm new in Solaris server
After the system support reboot the Solaris server, all the files in /tmp has been removed, is that normal under Solaris or under different init level will get different result?
which init level will do that?

when you have a look at you /tmp in your /etc/vfstab you will see that /tmp is mounted from swap as a tmpfs filesystem, a memory based file system:
see "man tmpfs"

You can dedicate a real filesystem slice to /tmp and that won't occur.

Thanks, fyi, I get another hp unix, the /tmp is not being cleanup after reboot the server

Is that the ideas is how the /tmp mapping into the harddisk or memory ?
not related to OS right?

TT

You might have a look at /etc/rc.config.d/clean_tmps which defines such a behavior on a hp system ...

I check it, that is correct, is that mean not depened on setup not the file system right? or both?
