Not true .. overlayfs is one way to have a read/write ISO, but
not the only.
This isn't something we bury in the middle of the ktypes. aufs
has always been a standalone configuration option, and one that
is enabled via KERNEL_FEATURES.
This is an alternative to the exiting aufs use case, and should
be treated a similar way (with a generic feature, an enable and
a disable). See the aufs fragments as a template to follow.
Sounds good, I will send a V2.
Hi Bruce,
After more investigations, linux-yocto 4.4 does have
features/aufs/aufs.scc,
but I can't find any source of aufs in kernel-source, I'm afraid that
linux-yocto doesn't merge aufs' patch. And when I added
aufs simply comes along later in the cycle. Since I do the
merges, I'd know if it was missed or not :)
features/aufs/aufs.scc
to KERNEL_FEATURES, I got this in merge_log.txt:
Value requested for CONFIG_AUFS_FS not in final .config
Requested value: CONFIG_AUFS_FS=y
Actual value:
Since overlayfs has been merged by mainline, maybe we can drop aufs
support ?
Nope .. aufs is still supported, since it has different features
than overlayfs. There is not "one union filesystem to rule them
all".
