Re: problem with incremental dump updates

 but I get lots of
 warning: cannot create hard link ./bin/uncompress-./bin/gunzip: File
 exists

Dump is probably complaining that it can't create a symbolic link because
the symbolic link already exists. It probably always archives symbolic
links, whether they have been recently created or not. It should lstat()
them and see if they point to the right place, and if so it should not
complain.

A recent alpha-test version of GNU tar emits this same complaint.

problem with incremental dump updates

[Carlos Carvalho]

I did a level 0 dump of a partition into another with the command

dump u0f - / | (cd /mnt; restore xf -)

Now I want to do a level 9 update, so that only what was changed since
the level 0 dump is upgraded. I tried

dump uf - / | (cd /mnt; restore xf -)

but I get lots of

warning: cannot create hard link ./bin/uncompress-./bin/gunzip: File exists

Am I doing something wrong? Is dump really able to only update what
has changed?
