Hi Martin,

quite easy using the ufs2ea-flip tool mentioned in the wiki page,
but it is not "plug & play".
- if FFSv2ea is not the default, most new installs will create non-EA
enabled file systems and
- the EAs will not get much testing
- packets from pkgsrc (like samba) will continue to have the corresponding
options disabled by default
- users will have a hard time to find the conversion options later.
It is hidden in fsck_ffs(8) and quite simple: after having made
sure your bootloader is up to date, boot to single user and
run something like: "fsck_ffs -c ea /"
So, what should be the default FFS type for new installs in netbsd-10 ?
given that switching to the new version is "relatively easy" after
install too, in both directions, I would conservatively keep using
FFSv2 as default, but suggesting EA for new installation without
interoperability issues, for this release.
If all goes well, for the next release, which would be 11, or even 10.1
(debatable) switch EA on.
Given, however, that ufs2ea-flip exists, I don't find it that menacing
to switch to EA by default.
