System: NetBSD tequila.dave.dtsp.co.nz 2.0G NetBSD 2.0G (TEQUILA-$Revision: 1.76 $) #1: Sat Aug 7 23:32:30 NZST 2004 firstname.lastname@example.org:/vol/tequila/userD/NetBSD-current/src/sys/arch/i386/compile/TEQUILA i386
The NetBSD 1.6 tar has a -y option for compressing using bzip2. The
new pax-based tar has a -j option that performs the same task.
Scripts that were written for NetBSD 1.6 may fail because of this
(trivial) incompatibility. The new tar doesn't use -y for anything
Use tar -y in a cron/disk based backup script. Notice that backups
mysteriously stop happening after upgrading userland.
1. Make new tar support -y as well as -j
2. Make new tar support -y instead of -j. -j hasn't yet been
supported in a NetBSD release.
3. Do nothing.
