That's all right, everyone knows that Salix users are "Lazy Slackers" and thus, being lazy, take the defaults. Which in this case is XFS :)

Well, this doesn't mean much really. Ext3/2 will still be supported, it's just that the ext4 driver will support those, instead of the ext3 driver, as ext4 is a superset of ext3. I think it's been like that for a while too.

is this

Code: Select all

[    2.467349] EXT3-fs (sdb2): error: couldn't mount because of unsupported optional features (240)
[    2.467625] EXT2-fs (sdb2): error: couldn't mount because of unsupported optional features (240)
result of driver removing? I use salix mate with kernel 4.1.4 on ext4 fs

No, this is the exact opposite. These messages show because the kernel tries to use the ext3 (and ext2) modules to access an ext4 partition. If the ext3/ext2 modules are removed, the messages will stop showing.

Put "rootfstype=ext4" on your boot command line and it should go away.
# Append any additional kernel parameters:

Code: Select all

append="quiet vt.default_utf8=1 rootfstype=ext4"
