I mean for a DNS server (all be it a small one) is it wise to use
compact flash as storage??
For our GSLB DNS Slaves, we boot embedded/low power (or even VMs these
days) systems with CF images off of flash, keep a shadow copy of /etc
around, and program all file systems with R/W activity
(/var/chroot/named/cache, where all zone files are fetched from Master
NS) on MFS partitions, eliminating almost all write operations to the
CF card.
No swap, and RD / (/var, etc.) and MFS /usr extracted from a tarball
via modified rc(8). /shadow is mounted noatime.
Are you saying that you custom compiled the kernel here??
I'm not that advanced with FreeBSD yet as I've only been using it for a
few months even though I have other UNIX based experience.

Where it gets risky is if you just plain install a live functional
FreeBSD on CF. A million inodes for /usr/src and CF is about as fast
as an ESDI hard drive in an IBM XT.
I was planning to go Standard Minimal Install then build Bind9 from
ports and of course use SSH as login system and perhaps hack out the
Serial port to give me some SPARC/POWER/Cisco style RS232c login.
From what you mention it sounds like a bad idea as the system disk will
have many R/W's going through it it seems as /tmp and Swap get written
to all the time.
I mean this would have been a cheaper alternative to buying an SSD drive
or SAS 2.5" drive but now I'm a bit worried.....
