Could you please enable CONFIG_BASE64?
base64 is normally guaranteed to be avialble because it’s part of coreutils.
But it is not in e.g. the initramfs.
While Debian’s busybox has in principle uuencode/uudecode as alternatives
enabled, these have a number of disadvantages, mostly their unsafe in interace
(see e.g. #995833).
busybox’ base64 seems to reuse the functions from it’s uuencode/uudecode, so I
guess the impact on additionally required space will be very little.
