SubjectPossible race condition


Dec 9 09:10:47 chaos kernel: VFS: Mounted root (ext2 filesystem) readonly.
Dec 9 09:10:47 chaos kernel: Adding Swap: 130748k swap-space (priority -1)

Linux chaos 2.1.14 #13 Fri Dec 6 16:19:43 EST 1996 i586

This occurs when setserial is executed in /etc/rc.d/rc.serial. The only
thing it sets is /dev/cua0 and /dev/cua1 which it will do fine interactively
after the system is up.

Further, if I comment out "swapon -a " so I am not enabling swapping at
the time, it works fine.

Possible race while enabling swapping????
