Use HOME before /etc/passwd to find id_dropbear (#137) Currently dbclient uses the value of HOME by default when looking for ~/.ssh/known_hosts, falling back to /etc/passwd if HOME is not set (so that people can work around broken values in /etc/passwd). However, when locating the default authentication key (defaults to ~/.ssh/id_dropbear), paths not starting with / are always prefixed with the value from /etc/passwd. Make the behaviour consistent by adjusting expand_homedir_path to use the value of HOME, falling back to /etc/passwd if HOME is not set.

#include <stdio.h>

int main(void)
{
   char buf[4096];
   int x;
   
   while (fgets(buf, sizeof(buf)-2, stdin) != NULL) {
        for (x = 0; x < 128; ) {
            printf("0x%c%c, ", buf[x], buf[x+1]);
            if (!((x += 2) & 31)) printf("\n");
        }
   }
}
