This is no different when using ZFS root. /tmp is, by default, a tmpfs file system. > Do we have any comparable option available when we use zfs root.

Yes, but the equivalent for a UFS root would be to format the swap device and change the partition size. Clearly, the ZFS solution is simpler and safer. > AFAIK in the ufs option for limiting swap size, we are just limiting the > filesystem behaviour of the tmpfs filesystem while the kernel will still be > able to use the swap space for paging etc. Is this correct understanding. By default, the Solaris 10 installer does not use UFS for swap. So there is no "ufs option for limiting swap size." -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
