Agreed, if it's a real solution. I'm not sure I've ever tried that,
particularly, so I can't say. I just went directly for the "stop the

You can. Whether there's a good reason [not] to do so is relative, of
When I first got a USB keychain I tried reformatting to ext2, but
now I keep it as FAT32 so that I can use the same keyring on any of
my operating systems and with very minimal runtimes. If you're
happily using only systems that speak ext3, then there's probably no
particular reason not to use ext3 on the USB drive -- but for the little
value that it gains you to do so, I'm not sure it makes sense to emplace
that restriction if it's not already there. I haven't found that using
a filesystem more "natural" to the host OS makes usage any more or less
My USB drive has statically-linked gpg executables for several platforms
on it, and multiple keyrings. (That's where "somewhat more complicated"
comes in; there's a shell script driver that accumulates options and
backends and such.) One goal of this arrangement is that I can perform
certain tasks on marginally-trusted systems outside my governance. Using
a broadly-available filesystem helps assure that remains an option, so
that I can consider whether it's wise independently of whether it's
This is perhaps somewhat off-topic, but it explains where my value
system comes from.
 Mainly MacOS and a couple of BSDs; but also sundry experimental
platforms, and Windows and Linux when I must.
 For example, booted from floppy or mini-CD.
