If you're going to respin it anyway, can you rename 'page' to 'buf'
or something? Kind of confusing to have a char * called 'page'.

is it really worth doing a strcpy() followed by a custom strtok()?
would this work better?
char c;
do {
c = *root_fs_names++;
*buf++ = c;
if (c == ',')
buf[-1] = '\0';
} while (c);

it occurs to me that get_filesystem_list() fails silently. if you build
every linux filesystem in, and want your root on zonefs (assuming
they're alphabetical), we'll fail to find it without a message
indicating that we overflowed the buffer.
