Thanx for the report.
Aufs is using colon in several options where an eaual sign specifies the
branch attribute such as RW and ROs.
Now I need to consider about all of them.
Currently
br:/upper=rw:/lower=ro
is the only option to take multiple branch specifiers.
Also this branch syntax appears in /sys/fs/aufs/si_XXX/br0, br1, ...
br0: /upper=rw
br1: /lower=ro
I believe they should be same to the mount option syntax.
"br=/upper=rw:/lower=ro" is not bad but I feel weird.
If I change "/upper:rw' syntax, that is not bad. But what is good to
delimit the branches?
Additionally there are other options using colon,
add:1:/middle=rw
mod:/upper=ro
append:/bottom=rr+wh
prepend:/new_top=rw+icex
Hmm, these options take only one branch specifier. It may be rather
easier than 'br' option. But I need to consider.
The option to remove a branch from the union is easy to replace.
del:dir
Other options using colon are not required to replace
create=tdmfs:low[:second]
create=mfs[:second]
create=mfsrr:low[:second]
create=pmfs[:second]
create=pmfsrr:low[:second]
I am still thinking...
