Another Exec format error 8-(

Running tcsh is different:
root@:/ # file /usr/bin/resizewin
/usr/bin/file: 1: Syntax error: word unexpected (expecting ")")

Running uname -a is more different, if not informative:
root@:/ # uname -a
/usr/bin/uname: dsp_traceflagp_tracevpvnodep_tracecredp_textvpp_lockp_sigiolstslh_firstsio_usiu_procsiu_pgrppg_hashpg_memberspg_sessions_counts_leaders_ttyvps_ttydpcdev_privs_ttypt_mtxt_mtxobjt_listt_revokecntt_inqti_firstblockttyinq_blockti_startblockti_reprintblockti_lastblockti_beginti_linestartti_reprintti_endti_nblocksti_quotattyinqt_inlowt_outqto_firstblockttyoutq_blockto_lastblockto_beginto_endto_nblocksto_quotattyoutqt_outlowt_inwaitt_outwaitt_outserwaitt_bgwaitt_dcdwaitt_inpollsi_tdlistselfdselfdlistsi_notekl_listkn_linkkn_selnextkn_knlistkn_tqekn_kqkqueuekn_keventidentu_short__intptr_tkn_statuskn_sfflagskn_sdatakn_ptrfilep_procp_aioaiocblistp_lioaioliojobp_nexttimekn_fopf_isfdf_attachf_detachf_eventf_touchu_longfilteropskn_hookkn_hookidknotekl_lockkl_unlockkl_assert_lockedkl_assert_unlockedkl_lockargsi_mtxselinfot_outpollt_sigiot_termiost_winsizews_rowws_colws_xpixelws_ypixelt_columnt_writepost_compatflagst_termios_init_int_termios_lock_int_termios_init_outt_termios_lock_outt_devswtsw_flagstsw_opentsw_open_ttsw_closetsw_close_ttsw_outwakeuptsw_outwakeup_ttsw_inwakeuptsw_inwakeup_ttsw_ioctlcaddr_ttsw_ioctl_ttsw_cioctltsw_cioctl_ttsw_paramtsw_param_ttsw_mode..........
Eventually it ends with Argument list too long and returns a prompt.

Two suspects are a corrupt download or a faulty microSD card.
However, running fsck -fy repeatedly finds, fixes and does not
find again the errors it fixed. Am I right in thinking this
largely exonerates the download and microSD integrity?

So far my luck with snapshots has been very good, but they
aren't guaranteed. Perhaps I should just wait for the next.....

There do seem to be two paths to armv7 snapshots. One is
/snapshots/arm/armv7/ISO-IMAGES/15.0/
and the other is
/snapshots/ISO-IMAGES/15.0/
Could the files possibly be different? The directory contents
certainly look different.... 

Thanks for writing!
