ramdisk.fs overflows

[Rin Okuyama <rokuyama%rk.phys.keio.ac.jp@localhost>]

These days, build fails because ramdisk.fs exceeds its limit:

(1) Dropping shutdown(8) as well as FFS_EI & Apple UFS support from
fsck_ffs(8) and newfs(8) reduces ramdiskbin about 34KB, and it fits
within the limit again. Note that FFS_EI option is not enabled by
default for all kernels of ews4800mips.

Alternatively,

(2) Dropping rcmd(1) and rcp(1) reduces about 20KB, and it also fits
within the limit.

Or any other choice?

Thanks,
